Ok, i have a setting in a gpo that runs a bat file that removes the file.
However, windows must create this file just after login, so the file comes back.
I have done the same on the logout script, but it means while the student is logged in, the folder is called my documents.
I have tried the settings in the gpo that has been mentioned for not creating them, but it does not work in out enviroment.
